i have looked through both stickys and i am virus and spyware free and for the tweaks i did have cablenut tweaks for my connection but i took them off when i had the problems but it didnt help any
whenever i use the 2992kb download test it hangs around 79% and when its done it shows my speed as very low one time even a -1 it does this on firefox and IE i have no router and no firewall
tried with the 12160 ( i think thats the size) and it hung around 21%
